Firefox Community Forum

When I restarted my computer, I was signed out of Firefox. I didn't remember my password and didn't realize creating a new one would deny me access to my bookmarks.

Can I recover my bookmarks? The restore function only lists today as an option after my new password was set (empty). I have no recovery key.

Hello, FF 139.0.4 on MAC Sequoia15.5. Lost ALL references to bookmarks, i.e. Bookmarks Toolbar totally gone. How can/do I restore from .jsonlz4 file in bookmarkbackups. Also, will I be able to salvage my previous profile, presumably containing my older "Tabs on Bottom" work-around? Alternatively, is there a process to restore JUST Firefox from Time Machine? Appreciate any advice.

The power went out in my area last night and When I turned my computer on this morning and opened Firefox, all my bookmarks are gone! It says the bookmark file is empty? I had many bookmarks that I use daily. How do I retrieve all my bookmarks I had in my Firefox account? Can someone help? Thank you.

I'm not sure whether i am in the correct forum. I have successfully copied to a USB stick the bookmarks from my old PC but, although I can open the html file and see them, I cannot see how to present them in the bookmarks menu. I am not recognising a simple "import" option such as I found with passwords. What am I missing

hello,

I want to transfer my profile from an old laptop to a new one. i am not comfortable with uploading my passwords to the cloud as i do not understand how this is safe. i made tar.gz file with the entire profile, almost 1gb and put that on the new laptop. edited the profiles.ini and install.ini and expected the profile will load, but firefox simply does not work in that profile. it cannot browse and clicking the menu button in top right does nothing. Please, help. If I share data below that is the working profile, not the one that fails.

Hi. I accidentally deleted the "Today" subfolder that exists under the "History" section in Mozilla. How can I get it back? I'm not interested in getting the internet history from today back, just the folder. Thank you for your help.

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

Basically, I reinstalled Windows, and I had all my passwords and stuff on my Firefox beforehand. Now, I don't remember my accounts password, and not the security key either.

My Firefox book marks have disappeared. The toolbar is open but has nothing to display.

I've gone to my Firefox Library window, but the entire page is blank. The table gives no entries for Name, Tags, or Location. Lines below (Name, URL, Location, Tags, and Keyword) are empty.

Searching my MacBook Air I found my Firefox Profile folder. In it there's a folder ending in "default-release". That folder contains a folder called "bookmarkbackups" containing files with titles indicating recent backups.

How can I restore my booksmarks?

Hi i have lost my bookmarks, comes up Import bookmarks, my sync is on, I have gone through and checked library and there are no backups, restore? No idea why this happened, they all just disappeared? Any other advice to try please?

I lost all my personal data on Firefox as soon as I changed the password and I did not know that you can lose everything that I had registered in the download box and the previous archive. Now I am very, very mentally disturbed and I do not feel safe and I am very sad about what happened to me. I am crying now. What should I do? My psyche is really broken due to the lack of information....

Synced my new computer, received bookmark toolbar and 10 year old bookmarks from when i switched from interent explorer, but all my more recent bookmarks and bookmark folders are still missing on the new computer. Also didn't seem to transfer passwords and autofill info.

Before reinstalling Windows, I made a backup, but since I didn't update the system until a day later due to work, I forgot the backup password. I've tried every password I could think of, and I don't know what to do now.

I was trying to Sort by Name, but hit Delete, because the right-click menu presentation shifted. No worries, Ctrl Z should undo on PC. Nope. Now I'm learning the only restore is through JSTOR/backup. I don't want to restore a previous state of operation. I want to un-Delete a folder. Is that a feature somewhere, somehow?

And secondly, can I force confirmation for all future folder deletions?

I'm trying to restore bookmarks after latest update. I get to the Import and Backup dropdown and pick Restore. there is nothing listed. I can go into my "C" Drive and find my "bookmarkbackups" folder and see the files. How can I get it reinstalled?

Upon restarting my laptop earlier today, I realized that ALL my Firefox bookmarks have disappeared into thin air. Gone (or, rather, "empty") is my bookmarks toolbar, and my bookmark menu, and everything else. What to do? Thank you.
